Roll forming is a continuous cold forming process that is characterised by high resource efficiency and productivity due to its high process speeds and up to 100% material utilisation. In order to obtain roll-formed products of high quality and at the same time reduce costs and set-up time, the innovative ‘partial rolling’ straightening process was developed for straightening roll-formed profiles. In contrast to conventionally used straightening methods, it enables the profile geometry to be controlled in a closed loop process. However, partial rolling has an effect not only on the profile geometry, but also on the profile properties.

The aim of this thesis is to investigate the side effects occurring during straightening by partial rolling with the aid of FE simulations and experimentally. The thesis contains the following work packages, which can best be discussed and, if necessary, adapted in a meeting:

• Development or adaptation of existing FE models
• Analysis of various side effects in FE simulations
• Experimental validation of the simulation results
